Ok so that’s like 3 reasons (the top 3) that affect conversions and 4 reasons that don’t to stuff the list out to 7 reasons? “Oh I’m just about to sign up with Gamble City but… hold on! hmm what is this affiliate’s privacy policy?” is something no one said to themselves ever.

I’ve got to disagree with you on that one. A Privacy Policy lets the users know what you’re actually going to do with the information they provide you. In the US, it’s required if you plan on ever contacting anyone via email. So, Privacy Policies are pretty important landing pages to have.
